Whats up everyone, I just bought a 325xi, and I had a question I figured one of you could answer. I just did a full tune up on my 325, oil, air filter, running 93 octane, and my car seems to have reaaaaaaallyyyyyy slow acceleration after 60 until about 80-90 then it picks up a little more. I have no mods in the car, fully stock. Very mint. Any suggestions on why this may be?
